Never heard about that, can you point me to read more about them? As I know thats not a simple chrome surface, it has silver, molibnenum and other materials and it has to be perfectly flat.

Do a search in the Rotary Car Performance section for "cermet":
https://www.rx7club.com/rotary-car-performance-77/
There are several threads of a few members who have done it.

The name of the website is jhbperformance.com look under the rotor housing section. They also offer coatings on the side housings as well. I have 3 sets of housings to be done but i'd like to hear from another person on the quality of their work or even results of usage if possible.

JHB is a mix bag.
In the early days I'd seen a few engines built with their coating fail in short order, on a HUGE scale. I'm talking coating missing from half the housing that got chewed up as it peeled off.
Have not heard of much negative stuff lately, but it seems to me alot less people are trying it nowadays given the lack of success back then. Plus, really, for the cost/risk factor - you're damn near the price of OEM housings in a bag from mazda by the time you get the coating done. And you *know* that the OEM housing will have no issues.
Sven from NRS has been working on a repair/coating process using similar chrome material to the original, this should work much better, but there's still no telling when or even if that will come to be.
